Structure and Pin Assignments
Straight-Through Cable
A 100-ohm DB9-to-RJ45 cable is 3 m long by default. If the default length is not enough for cable connection, you can use a straight-through cable as an extension cable.
When using a straight-through cable to prolong a 100-ohm DB9-to-RJ45 cable, connect one RJ45 connector of the trunk cable to a network interface connector and the other RJ45 connector to the remote device, as shown in Figure 8-21.
Connection
A 100-ohm DB9-to-RJ45 cable is connected as follows:
- The DB9 connector is connected to a router.
- The RJ45 connector is connected to a network device.
Ordering Information
If 100-ohm DB9-to-RJ45 cables need to be prolonged, configure one network interface connector and one straight-through cable for each 100-ohm DB9-to-RJ45 cable.
Table 8-33 provides the 100-ohm DB9-to-RJ45 cable ordering information.
